Full cycle now automated:
1. Delete old extrude (if exists)
2. Delete old sketch (try ReplaceFeatureBuilder first, fallback to delete)
3. Create new sketch with rib geometry
4. Extrude new sketch by rib thickness along face normal
5. Name both features for identification on next iteration
Rib thickness read from profile JSON (parameters_used.thickness)
with fallback to geometry JSON or default 10mm.
No more manual extrude step needed between iterations.
Replaces naive ReplaceEntity approach with NX's proper
ReplaceFeatureBuilder API. This mirrors the interactive
right-click → Replace Feature workflow:
- SelectFeature: old sketch to replace
- ReplacementFeature: new sketch taking over
- DoAutomaticGeomMatch: auto-maps curves
- DeleteOriginalFeature: removes old after remap
- Fallback: manual delete if builder fails
All downstream features (extrude, trim) automatically
re-reference the new sketch.
Complete rewrite of triangulation engine:
- Regular hexagonal-packed vertex grid (equilateral triangles)
- Density-adaptive refinement: denser near holes, coarser in open areas
- Boundary-conforming vertices along frame edge and hole keepouts
- Delaunay on point set + clip to valid region (inside frame, outside keepouts)
- Result: proper isogrid layout, 87 pockets from 234 triangles
- 553 NX entities, min fillet 4.89mm, mass 2770g
- No more dependency on Shewchuk Triangle library (scipy.spatial.Delaunay)
- Switched to uniform triangulation (no density-adaptive refinement for
initial pass — saves that for stress-informed iterations)
- s_min=45mm, s_max=55mm (was 12/35) — larger triangles fit 6mm fillets
- Boss keepout circles: 12 segments (was 32) — less boundary clutter
- Fillet must be >= 80% of r_f at every corner or pocket is skipped
- Result: 75 pockets, 481 NX entities, min fillet 4.85mm, mass 4066g
- adaptive_density=True param enables density refinement for future stress iterations
- Default r_f raised from 1.5mm to 6mm (machining constraint)
- Default min_pocket_radius raised to 6mm
- Pockets that can't fit r_f at any corner (within 80% tolerance) are
skipped entirely — left solid for more stiffness in tight areas
- Result: 26 pockets (was 432), 187 NX entities (was 13,061)
- Min fillet radius: 4.88mm, all >= 4.8mm (80% of 6mm)
- Mass: 4,601g (was 3,480g — more solid = heavier but manufacturable)
Model curves (part.Curves.CreateLine) are SmartObjects that can't be added
to a sketch via AddGeometry. Switch to SketchLineBuilder which creates
native sketch geometry directly (SetStartPoint/SetEndPoint/Commit).

Generates publication-ready PSD figures from OP2 FEA data:
- psd_multi_angle.png: PSD curves for all elevation angles
- psd_band_decomposition.png: LSF/MSF/HSF bar chart
- psd_40deg_composite.png: WFE surface + PSD side-by-side
- psd_trajectory.png: Band evolution vs elevation
Uses Atomizer's full OPD pipeline for consistency with CDR WFE numbers.
- tools/wfe_psd.py: Quick PSD computation for WFE surfaces
- optimization_engine/insights/wfe_psd.py: Full PSD module with band
decomposition (LSF/MSF/HSF), radial averaging, Hann windowing,
and visualization support

Session insight from stopp command implementation
PSD analysis decomposes WFE into spatial frequency bands per Tony Hull's
JWST methodology. Used for CDR V7 to validate that MSF (support
print-through) dominates the residual WFE at 85-89% of total RMS.
- X-axis now auto-ranges from data (was going to 10^21)
- Band annotations clamped to actual data extent
- Legend moved to upper-right (was overlapping data)
- Thicker lines (2.5px), larger axis labels
- dtick=1 for clean log-scale tick marks
- Band RMS now uses direct Parseval: sqrt(sum(|FFT|²) / N⁴ / hann_power)
- Previous approach had dimensional mismatch (cycles/apt vs cycles/mm)
- Results now match Zernike filtered RMS within ~10%:
40° vs 20°: PSD=6.18nm vs Zernike=7.70nm
60° vs 20°: PSD=15.83nm vs Zernike=17.69nm
90° Abs: PSD=27.01nm vs Zernike=22.33nm
- PSD plot curve uses separate normalization (shape, not absolute)
- Refactored compute_surface_psd to return dict with freqs, psd, bands
- Remove compute_spatial_freq_metrics() and _spatial_freq_html()
- Add compute_surface_psd(): 2D FFT + Hann window + radial averaging
- Add compute_psd_band_rms(): gravity/support/HF band decomposition
- Add make_psd_plot(): interactive log-log PSD plot with band annotations
- Add _psd_summary_html(): band RMS cards with % breakdown
- New section in report: Power Spectral Density Analysis
- Zernike details now show only coefficient bar charts (cleaner)
- Methodology: Tony Hull JWST approach for WFE spatial frequency analysis
